ADJUSTABLE AND FOLDING SHUTTER OR SCREEN.

SPECIFICATION forming part of Letters Patent No. 573,659, dated December 22, 1896.

l Application filed August 10, 1896. Serial No. 602,219. (No model.)

To all whom, it may concer/t.-

Be it known that I, OLOF IIOYER, a citizen of the United States, residing at Chicago, in t-he county of Cook and State of Illinois, have invented certain new and useful Improve- .ments in an Adjustable and Folding Shutter or Screen, of which the following is a specification.

This invention relates to improvements in an adjustable and folding shutter or screen for windows, doors, and the like; and it consists in certain peculiarities of the construction, novel arrangement, and operation of the various parts thereof, as will be hereinafter more fully set forth and specifically claimed.

The objects of my invention are, iirst, to provide an adjustable and folding shutter or screen for windows which shall be simple and inexpensive in construction, and strong, durable, and effective in operation; second, such a shutter or screen in which the leaves or slats thereof may be adjusted to any desired angle to admit of ventilation and to regulate the admission of light; third, to provide a shutter or screen which may be raised and folded together at the top of the casing into a compact form, and, fourth, to provide a means whereby the leaves or slats forming the shutter or screen may be locked in position so that they cannot be raised from the exterior of the building.

In order to enable others skilled in the art to which my invention pertains to make and use the same, I will now proceed to describe it, referring to the accompanying drawings, in which- Figure l is a view in front elevation of my improved shutter or screen, illustrating it foreshortened for the convenience of illustration and showing the slats or leaves in their normal position. Fig. 2 is an enlarged sectional view taken on line 2 2 of Fig. l, showing by dotted lines the slats or leaves raised to an angle to admit of light and ventilation. Fig. 3 is a like view of a portion of the shutter or screen, showing the slats or leaves raised and folded together. Fig. 4 is a crosssectional view, taken on line 4 4 of Fig. l, of a portion of the guide and locking tubes, a part of one of the rods which supports the slats or leaves, and a lock for securing the said rods, but with the casing omit-ted.v Fig. 5

is a sectional viewtaken on line 5 5 of Fig. 4, showin g the guide and lockingtubes, thelock therefor, and a portion of one of the bars or rods to support the leaves. Fig. 6 is a view in elevation, partly in section, of the guidetube, locking-tube, and rods for supporting the leaves or slats, showing them secured together by means of a chain. Fig. 7 is a detail plan View of the guide and locking tubes and a lever for turning the latter. Fig. 8 is a perspective view of a portion of one of the locking-tubes; and Fig. 9 is a vertical sectional view of one of the guide-tubes and a locking-tube therein, showing springs at the ends for actuating the latter.

Similar letters referto like parts throughout the dierent views of the drawings.

A represents the casing or frame,which may be made of any suitable size, form, and material to iit within the window-casing or doorway. To the inner surface of each of the side pieces of the casing is secured a guidetube B, which is provided with a vertical slot b for the reception and operation of the supporting-rods C, which are formed at their ends Vwith button-heads c to prevent their removal from the slots of the guide-tubes, which eX- tend from the lower portion of the casing to near its top. IVit-hin each of the guide-tubes B is placed a locking-tube D, which is likewise provided with a longitudinal slot d for the passage of the supporting-rods C for the leaves or slats C', which form the shutter or screen. The locking-tube is provided at suitable distances with recesses d', which open into the slot CZ of said tube and are adapted to engage the supporting-rods, as is clearly shown in Figs. 4 and 5 of the drawings. The guide-tubes B are secured to the side pieces or walls of the casing by means of suitable brackets h', which are fastened to said walls by means of screws or otherwise. The guidetubes and locking-tubes are formed with openings 192 and cl2, respectively, for the reception of the locking-bolt E when it is desired to prevent the locking-tube being turned within the guide-tube. This locking-bolt E has a shank E' at right angles thereto, which is formed rectangular at its outer end to receive 'a kej7 of such a shape used for turning the same. The shank of the bolt E is placed i'n a tube E2, which is embedded in the wall or IOO side pieces of the casing, as is shown in Fig. l of the drawings. On the top of each of the locking-tubes is secured a lever F, which are united together by means of a bar F', which is pivoted at its ends to said levers. One of these levers has secured to it a cord g, which passes over a pulley g and depends to a suitable distance to be used for operating the levers when it is desired to turn the lockingtubes. Secured to the lower rod C near its ends are chains or cords e, which pass over suitable pulleys e in the top of the casing, and are then united, which united portion depends to a convenient height to be reached when it is desired to raise or fold the leaves of the shutter or screen. The leaves or slats C' maybe made of any suitable material and secured in any desired manner to the supporting-rods C, and have on their lower edges rings or eyelets c for the reception of one or more cords C3, which may be passed over a pulley C4, located near the top of the casing, as is shown in Fig. 2 of the drawings, by means of which cord the slats maybe adjusted to any desired angle, as shown by dotted lines in Fig. 2, to admit of light and ventilation.

lVhen it is desired to fold the shutter or screen, the chains e may be drawn over the pulleys e' therefor, which will lift the lower rod and its slat until it reaches the one just above it, and so ou until the top of the shutter is reached, when the chain may be secured and the slats forming the shutter or screen securely held in a folded and raised position.

To prevent the shutter or screen being raised or folded, the locking-tubes D within the guide-tubes may be turned by drawing` the cord g, which is connected to the levers F on the upper portions of said locking-tubes, which operation will cause the recesses d to engage the rods C, as is apparent by reference to Figs. 4: and 5 of the drawings, in which position the tubes may be locked by means of the bolt E, which, as before stated, is located in the side pieces or walls of the casing.

It is obvious that in order to make a screen of the device all that is necessary is to place on the rods C strips of wire-cloth or other suitable material which will act in a similar manner to the slats or leaves forming the Near the ends of the rods C is secured-a chain e3, which serves to hold the rods at a proper distance apart to lit within the recesses of the Vlocking-tube.

In the upper and lower ends of the lockingtubes D is fitted plugs N and N', respectively, to the former of which are secured the levers F for turning the locking-tubes.

Around each plug is a spring n, which are secured at one of their ends to the plugs and at their other ends to the pieces O and O in the guide-tube, which form bearings for the plugs. v

Having thus fully described myinvention.,

what I claim as new, and desire to secure by Letters Patent, isl. The combination with a casing, of a slotted guide-tube secured to each of the walls thereof, a locking-tube, havinga vertical slot and a number of recesses, located in each of the guide-tubes, a lever on each of the locking-tubes, a device to turn the levers, a series of rods carrying slats or leaves located in the slots of the tubes, and chains or cords to raise said rods and to adjust the angles of the slots or leaves, substantially as described.

2. The combination with two upright tubes each having a longitudinal slot, of a lockingtube having a longitudinal slot and a number of recesses, and located within the first-named tubes, a lever on each of the locking-tubes, a device to turn the levers, a series of rods each carrying a slat or leaf, andl located transversely within the slots of the tubes, chains or cords to raise the rods and to adjust the angles of the slats or leaves, and bolts to lock the locking-tubes within the tubes which surround them, substantially as described.
